Duplicating a CD or DVD

You can use Disk Utility to quickly make copies of a CD or DVD and the information it contains.

To do so, first you create a disk image of the CD or DVD. Then you use the disk image to burn copies of the disc.

  1. Insert the CD or DVD disc in your computer's optical drive and select it in the list of disks and volumes.
  2. Choose File > New > "Disk Image from (name of disc)."
  3. Type a name for the disk image and choose an image format.
  4. To require a password to access the contents of the disk image, choose "AES-128 (recommended)" from the Encryption pop-up menu.
  5. Click Save.
  6. When creating the disk image finishes, eject the original CD or DVD.
  7. Select the disk image in the list and choose Images > Burn.
  8. When the Burn Disc dialog appears, insert a blank CD or DVD.

    To select additional options, such as making the disc appendable, click the triangle in the top-right corner.

  9. Click Burn.

You can continue using the disk image to create as many duplicate discs as you need.
